A hub is formed as part of the knob. A shaft receiving socket is formed in the hub. The socket has a flat wall adapted to engage a flat surface on the shaft. A resilient finger is formed as part of the hub and extends into the socket upwardly from the flat wall. The resilient finger is positioned to engage an arcuate side of the shaft when the shaft is inserted into the socket so as to slightly deform the resilient finger and thereby apply a force to the shaft. The wall of the socket located opposite the flat wall is semi-hexagonal and the resilient finger extends towards but terminates short of the semi-hexagonal wall. | |
